Abstract:
A deployable measurement system for analyzing a rail of a railroad track includes a housing, a reflecting assembly coupled to the housing, a movement assembly coupled to the housing, and an optical measurement system disposed within the housing. Both the housing and the reflecting assembly are moveable between a stored position and a deployed position. The movement assembly includes a deployment assembly that moves the reflecting assembly from the stored position to the deployed position, and a retraction assembly that moves the reflecting assembly from the deployed position to the stored position. The optical measurement system emits and receives light. The reflecting assembly reflects the emitted light toward the rail. The reflecting assembly reflects light reflected off of the rail toward the optical measurement system. The light received by the optical measurement system is used to measure parameters related to the rail.
Abstract:
A device consisting of a digital camera with a microscope objective lens, a disc where plant material can be mounted and automatically rotated, and two other cameras for determining the plant material's shape and size, that allows images of intact cannabis trichomes to be taken, without destruction or damage to the plant material, and automatically counts and calculates the density of the trichomes on the inflorescence surface. This does not require taking any plant cuttings, does not require the use of a microscope or microscope slides, and allows multiple measurements to be taken of a single inflorescence sample in quick succession, without the need for manual image analysis.
Abstract:
A method and apparatus for establishing a pathway for performing an automated validation of a condition of assembly. A sensor system coupled to an automated guided vehicle is moved into test positions relative to the structure. Image data is generated at each test position, using the sensor system, to build test images. Each test image is registered to a computer model of the structure to form registered images that are added to a collection of registered images. An optimal set of positions that will allow an entirety of an area of interest to be captured using a fewest number of registered images from the collection of registered images is determined. A pathway is generated for moving the automated guided vehicle to each optimal position in a least amount of time. A computer file identifying the pathway is generated for use in performing the automated validation of the condition of assembly.
Abstract:
One embodiment provides a method for identifying a target object of a pipe wall, including: positioning a pipe inspection robot within a pipe; emitting, using a terahertz (THz) beam source of the pipe inspection robot, a laser beam towards a target object; receiving, using a THz receiver of the pipe inspection robot, THz data related to the target object; analyzing, using a processor, the THz data; and determining, based on the analyzing, an identity of the object. Other aspects are described and claimed.
Abstract:
A method of detecting natural gas releases that includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of methane in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.
Abstract:
Systems for very early smoke detection are disclosed, including details of tube hangers that may be used to hang sampling tubes for very early smoke detection systems. The systems and components thereof may be temporarily installed in aerospace vehicles during manufacturing. The tube hangers are generally compact, allowing use in confined spaces and/or near obstructions. Tube hangers comprise a support coupling mechanism, a tube clamp, and one or more suspension arms that span between the support coupling mechanism and the tube clamp. Tube hangers may be a unitary body that defines a tube clamp, one or more suspension arms, and a support coupling mechanism. Tube clamps define a tube clamp opening generally facing away from the support coupling mechanism.
Abstract:
A method for detection or the density determination or the classification of an aerosol using spectroscopy includes: using an image taken by a camera for a vehicle, a first value of a parameter being ascertained from the at least one image in a first step, using a first color filtering, and a second value for the same parameter being ascertained in a second step having a second color filtering, which is different from the preceding color filtering, and the values ascertained in the at least two steps are compared, and as a function of the result of the comparison, the detection or the density determination or the classification of the aerosol is carried out.
Abstract:
A system and method for in-field near infrared spectroscopy (NIRS) analysis of rubber and resin concentrations a guayule plant is provided. The system includes a wagon or other vehicle with the NIRS device mounted on the wagon. A computer or processor electrically coupled to the NIRS device is also housed within an area or extension of the wagon. During measurement of a guayule plant in the field, a guayule plant covering is placed over the guayule plant and a light shield coupled to the NIRS device is inserted into an opening on the guayule plant covering. The NIRS device is configured to perform a reading of the guayule plant within the plant covering and communicate results of the reading to the computer. A calibration equation is then preferably applied to the guayule plant readings to produce the rubber and resin concentrations of the guayule plant.
Abstract:
The invention relates to a measuring device for determining a vegetation index value (REIP) of plants. The measuring device comprises a plurality of light emitting elements, each of which emits substantially monochromatic light at a predetermined wavelength, a light receiving element which receives light from the light emitting elements reflected by the plants and generates a signal indicating the respective intensity of the received light, and a control means which successively activates the light emitting elements in a cyclical sequence, determines the respective intensity of the reflected light based on the output signal of the light receiving element, and calculates the vegetation index value based on the determined intensities of the overall measurement cycle. According to the invention, a light frequency converter is provided as the light receiving element.
Abstract:
A Raman spectroscopy sensor integrated with an unmanned ground vehicle (UGV) includes a UGV having a robot arm and a camera mounted on the robot arm. A laser and telescope associated with a Raman sensor are mounted on the robot arm in such a way as to point in substantially the same direction in which the camera is pointed. A Raman spectral data acquisition and control module is mounted on the UGV and is configured to receive Raman spectral data from the telescope. A remote base station having a display and a data processing and analysis module is configured to receive data from the data acquisition and control module and to display for an operator images from the camera and information related to the Raman sensor. An autofocus system is preferably employed to automatically control telescope focus and thereby enable the Raman sensor to operate over a wide range, e.g., 0.5 m to 10 m.
